Now I just need to alter my port, so I can start having a round robin Vs. battle between all the monsters to rank them. This will help with improving the AI (if you can call it that), which currently does some silly things.

Should be able to start cross referencing the unknown affects and things.. Nobody but trolls have the affects it has so one of them must be regen… and wyverns + medusae share affects so the 40 cant be stoning..

This is awesome information! Saves me from having to figure it out from testing. But I was wondering, was there other monster data that wasn’t posted?

For example:
there should be something that toggles whether to use the first set or second set for weapon damage (i.e. whether a two-handed sword does 1d10 or 3d6)
since some 1×1 icon monsters, such as the beholder and the giant spider, will still count as a large monster.
Also, rangers get the +1 per level bonus against certain monsters like the troll and the ogre (and presumably the bugbear and ettin, although I haven’t tested them yet), but I don’t know what’s the complete list
and I haven’t found any monsters against which dwarves/gnomes get the “man-sized giant-class” bonus mentioned in the manual

There’s heaps of data, I just posted the things I though were the most interesting or I completely understood.

The weapon selection is done in code, based on lots of stuff.
The monster size is known, and defines if it’s 1×1, 2×1, 1×2 or 2×2
Rangers bonus is an affect added at player creation, but no monsters are rangers, so they don’t have this affect.

Oh I meant how does the game know for which monsters should you do normal damage (i.e. 1d10 for the two-handed sword) to, versus larger-than-man-size damage (i.e. 3d6). It doesn’t seem to strictly be based on the icon size, since you do the latter type of damage against beholders and giant spiders and possibly others that are 1×1. Similarly, rangers deal extra damage to certain monsters like trolls and ogres; same with the flame tongue, dragon slayer, and frost brand swords. I imagine the game would have some sort of flag or affect for that.

Currently, I’ve just been slowly going through the game and testing the monsters one by one for those things. Naturally, it’s pretty slow going, so having those affects would come in handy for figuring them out.

Literally by save-loading and fighting battles and recording the damage that I do. Based on the minimum and the maximum values that I see over lots of trials (basically until I see the full range of values), I can figure out if there’s bonuses. For example, against the hell hound, with a dwarf fighter/mage/thief with strength 18(99), the long sword +1 flame tongue does 7 to 18 damage, +2 dragon slayer does 8 to 19 damage, and +3 frost brand does 12 to 23 damage. Therefore, since str 18(99) gives 5 damage bonus, and the range (spread) of the long sword is 8 (1d8) vs regular targets, and 12 (1d12) vs large targets, I can conclude that it’s using the “large” damage set (i.e. the monster has a “large” flag) and that the hell hound takes an extra 3 damage from the frost brand.

From this, I’ve figured out stuff like that rakshasas take half damage from weapons that are +2 or less, and that the dragon slayer (apparently) does 3*(1d11) + 4 damage against dragons, although it might be 3*(2d6) + 1 damage instead (both will give the same values for damage).
